Thanks for the quick replies on airspeed indicators for sail. I thought I was looking at $1100 for a new one. But, Turns out there is a Avionics Fix It shop south of here about 50 miles that will do an overhaul for $350 so I'll do that, because then I keep the color bands appropriate for the airplane. Its not for my RV. Its for a Cherokee Vne = 173 kts.
